About Rebel Athletic

At Rebel Athletic, we don't just make apparel. We create confidence, empower performance, and redefine what it means to wear your passion.

Since 2012, we've disrupted the industry as the fastest growing cheer and performance wear brand in the world. Recognized by global brand consultancy Eat Big Fish as a Challenger Brand to Watch, Rebel is known for bold design, innovation, and unmatched custom craftsmanship.

From couture-inspired uniforms to elevated athleisure, we blend high fashion with high function. Every piece is built for athletes and performers who want to stand out, not blend in.

Founded by Karen Aldridge, Rebel started as a bold idea and grew into a global movement that celebrates creativity, individuality, and empowerment.

Our business is rooted in a made-to-order team and group orders. We partner directly with teams, gyms, studios, and program owners to design and produce custom uniforms, costumes, and performance apparel at scale. This collaborative approach brings each program's vision to life through high-quality, fully customized pieces built for both performance and impact.
